High Temperature Mass Spectrometric Study of the TiO2–Al2O3 System

The results of studying the evaporation and thermodynamic properties of the TiO 2 –Al 2 O 3 system in the temperature range 2250–2710 K by high-temperature mass spectrometry are presented. The composition of the vapor is identified, the partial pressures of the TiO 2 , TiO, and Al vapor species over...

Zusammenfassung:The results of studying the evaporation and thermodynamic properties of the TiO 2 –Al 2 O 3 system in the temperature range 2250–2710 K by high-temperature mass spectrometry are presented. The composition of the vapor is identified, the partial pressures of the TiO 2 , TiO, and Al vapor species over the studied samples in the indicated temperature range are determined. The determined activities of the components and the excess Gibbs energy in the melt of the TiO 2 –Al 2 O 3 system at 2345 K point to insignificant deviations from ideality.
